The Glock 17 Gen4 in 9mm introduces revolutionary design changes to the Glock that dominates the Limited Class of competitive Shooting Sports worldwide. Internally, the Glock dual recoil spring assembly substantially increases the life of the system. A reversible enlarged magazine catch, changeable in seconds, accommodates left or right-handed operators. The surface of the frame employs the scientifically designed, real-world-tested, Gen4 rough textured technology. The modular backstrap design lets you instantly customize its grip to adapt to an individual shooter's hand size. The G17 Gen4 retains the Glock accessory rail for your attachments. Glock engineers have developed the Glock Modular Optic System (MOS) to simplify mounting of popular optics without costly custom machining of the pistol's slide. The MOS is offered with cover plate when no optic is mounted and four plates options to comply with the specifications of some of the most trusted optic manufacturers in the industry.
